Compliance is the proportion of times the two MPs in a pair vote the same way in a given session. Similarity is the average vote similarity between the two MPs in a pair. Neighbor is a dummy variable equal to one if the MPs in the pair are randomly assigned to sit next to each other during that session. Corner is equal to one if at least one MP in pair has only one seating neighbor. Middle is equal to one minus Corner. Dyadic-robust p-values are in square brackets. Randomization inference p-values (1000 draws) are in curly brackets. Special sessions and a short session (2017) are excluded. For lead and lag specifications, sessions are also dropped where lead/lag would be a special/short session or a session in a different parliamentary term. *** p<0.01, ** p<0.05, * p<0.1.} \\ \end{tabular} }
